I believe it's to keep the hall effect as high up as possible, so that it will always be in viewing range of the floating magnet. If it was at the bottom (laid flat against the PCB), it would already be a solid 1-2" inches away from the floating magnet, which is close to the maximum range for most hall effects.
This analog circuit seems to be pretty fast at response. Microcontroller based levitation circuits are generally slower due to the processing time of the microcontroller. Op-amp based or descrete logic based levitation circuits are very fast. You may think of an FPGA based levitation circuit. Love from India. ❤️
Hello sir, can you please tell me how it is controlling linearly with respect to magnet position, is it based on PWM or something? How controlling signals are applied to the H bridge driving circuit? Thankyou in advance
Thank you for putting together this video. I purchased this product from Aliexpress but was surprised when there were no English instructions. I'm not (yet) a schematics reader, but it looks like your video and instructions will be very helpful. Much appreciated - thank you!
I purchased a diy kit but unable to make it work. I was sent a debugging guide showing a multimeter connected where the jumpers are placed. You have to adjust each one (Y & X) to zero amps, but mine is not reading anything :( The led only lights when the floating magnet is placed above, which is correct. What could I check to determine what is wrong with mine? Is there a way to check the coils to make sure they are working?
I have this kit, but I'm not able to levitate! The 2 adjustable pots (blue boxes) must have some "starting" value, but I do not know what that value is. Can you make the schema where you soldered the wires and use them as input on tour oscilloscope, so I can measure the values? What are your values? Thank you for your videos and help!
Same issue here. It seems like the Hall effect sensors are working and triggering the transistors but the fields aren’t balanced at all and the platform just falls to whoever side it’s closer to
Your work and effort to share knowledge is pricesless. That's why channel should get millions of views and subscribers. Awesome job in explaining this magnetic levitator 😍
It's interesting, I'm thinking that by using an Arduino to control the levitator you should be able to control de position of the magnet in all 3 axis right?
how much weight does this top part carry to see it I could put a pot or a globe on it? Also how heavy is the bottom of the magnetic levitator. Also is there a way to reduce the weight of the magnetic levitator. Thank you.
Mine when i turn it on the big magnet just snaps to one of the smaller ones at the side. No matter how in center i place it it randomly jumps to one of the magnet. Any solution what I could do wrong ?
Hi man, I'm a big fan. I have bought one of those kit and build it, it does not work. The led is on when there is no magnet and one of the B772 failed (got very hot) Can you please help, Thanks
MikeRoss1986 no. I have two modules. One that tilts badly to the side and the other is having the same issue as yours. Please let me know if you figure it out too please.
I am so grateful to see someone taking the time to explain the actual things you need to know. Quick question: I am assuming the potentiometers are for calibration. Do they help with accuracy or height of levitation. If you have played around with these potentiometers, can you please share some info on what do they allow you to adjust. Thank you.
I can't get mine to work, the LED lights up when the magnet is close but the magnet just slides to the side. Any advice? I can't find any documentation in English for troubleshooting...
Hi and thanks for sharing this project. Is this project completed? I'm asking because you marked the project as ongoing in oshwlab . And where is the top part of your design? Thanks
Can upgrade and make magnet locked so there is high resistance so you can't push down, so the magnet bouncy is much less, the up and down magnet field is less too, so you increase the magnet field, you decrease up and down so you locked it so can't push up.
What are the coils parameters? How many turns in each layer and how many layers? What is the wire diameter? Does it contain iron core, or it wired around plastic with nuts on top and bottom? What inductance have that coils?
@@limtbk I don't know how many turns, The wire diameter is 0.25, the inner aluminum screw is 7mm diameter and the coil is 19mm diameter and 11mm height.
@@limtbk well, not really, that would be without the clearance. The amount is way lower. Here I've uploaded some photos for you. I count 30 layers and each layer has around 9 turns.

Hey just went through the video. Its so amazing how you have mentioned all the details. Also i went through the files But unable to find BOM list. Could you help me with the same?
If you refer to the Chinese schematic, or an ohm meter, you'll notice the X and Y sets of coils are connected in series. The opamp Hall control only modulates the field strength of the entire axis, not individual coils. If the magnet wanders up or down in the Y axis, the Y power will drop and likewise in the +/- X axis. The Z axis is only used for the comparator to turn on the circuit in the presence of a magnetic field.
Absolutely correct, can you please tell me how it is controlling coils power linearly? , is it based on PWM or something? How controlling signals are applied to the H bridge driving circuit? Thankyou in advance
Don't know what coils they are, but you can probably make your own. The wire looks like it might be 24 or 26 AWG with about 20 or so layers. Not sure how many turns per layer or what the core is made of, but it looks like it might be aluminum and if the magnets are 5cm, then the overall coil length is approximately 15 cm. With something to serve as the core for wrapping, a few nuts, washers, bolts and varnish, you should be able to make something close to the ones supplied in an afternoon. I, personally, like to use bobbins for sewing machines as they are pretty inexpensive and leave you with nice looking coils.
I have tried your pcb design and found few issues which is 1. 78L05 is not connected to ground 2. Resistor values are wrong to maintain floating magnet
can I make the coil by my self? I'm living far away from your country, it takes forever to order from you. let say I can print the PCB locally in my city, but I dont know how to build the coil. can you show me the way? Im really interested to this project
Hi how are you? I have a question for you.I want to build tiny home without wheels and how can I float it on the air ? Can I use magnets and what kind of technique? Thank you
I've built the circuit and the LED remains on until the magnet is presented, at which point it turns off. It seems the Z hall effect sensor is de-activating the circuit rather than activating it. Any ideas what I might have done wrong? I can feel the coils having an effect on the magnet just before the LED turns out.
Well, I inverted the permanent magnets around the edge and the led works as intended now but that's all that happens. I can't get it to balance. Any tips on tuning?
Can it lift up by itself if you put a magnet under the Electric Plate, so that your levitation Magnet Lifts another magnet -/- unter the Plate magnet ???? You know what i mean ??
2:09 Dude, lower your soldering iron temperature, you are going to rip some tracks at that temperature. High temp is good for groundplanes, where your soldering iron doesn't have too much power, but you're relying on the thermal inertia.

This is pure gold! Thank you for explaining it in so much detail.
Amazing tutorial! can you tell me what is the need to keep the hall sensor as tall as the coils???

If it was at the bottom (laid flat against the PCB), it would already be a solid 1-2" inches away from the floating magnet, which is close to the maximum range for most hall effects.

I'm asking because circuit itself is not big deal, all components are standard. But coils are not. And that's prevent me to repeat that scheme.
@@limtbk I don't know how many turns, The wire diameter is 0.25, the inner aluminum screw is 7mm diameter and the coil is 19mm diameter and 11mm height.
@@ELECTRONOOBS So, we have (19-7)/2/0.25=24 layers, each have 11/0.25=44 turns, so about 1000 turns in total
